Specification of Letters Patent.' Fatgmt-@d @ya 159 1921.

Application filed September.' 29, 1919;` Serial No. 327,252.

To all 'whom t mag/concern:

Be it known that l, WiLLiAir EHRLICH, 'a citizen of the United States, residing at Chicago, in the county of Cook and State ot Illinois, have invented certain new and useful improvements in Pie-Making, Machines, of which the following is a specification.

My invention relates to pie-making machines and has for one of its objects the pro-` vision of simple and Vefficient 4means for crimping and sealing the crusts of pies.y

A further object is` the lprovision of a crimping machine for pie-making machines in which the device moves along.y with the pies while the crmper is `in engagementwith the pies so asto prevent/tearing such pies.

Another object is theprovision of a crimpino device for pie-making machines which can be thrown out oit' gear only at a predetermined position in its cycle of movement and which can only be thrown into operative condition when in a predetermined position of its movement and all in timed relation to the movement of pies adjacent the crimping device.

A still further objectv is the provision of providing means` for preventing. scraps of pies and vother foreign material from getting into the conveyer vpart of the apparatus.

*Other objects will appear hereinafter.

An embodiment of my invention is illustrated in Athe accompanying drawings,

forming a part of this specilcatiom' and inl which- Figure 1 is a plan view emloodyingmyy invention Fig. 2 isa vertical cross-section taken'V on line 2-2 of Fig. 1;

Fig. 3 is a side elevation of a fragment ofl0. is, an` endless conveyei and travels sub- Adjacent one end stantially horizontally. of the.- device is Va cutting bar 13 and a cutting wheel 13 positioned so that as the pies,l travel around the end ot the conveyor the by severing vthe protruding edges of the pie crusts. i

.Attached to the conveyer 10 is a vplurality of members, 14, which have sliding surfaces .15 `engaging the tracks 11 to support the conveyer 1 0. rlhesemembers 14 have vertical openings therein providing ybearings 1for upright spindles16, and `on the upper ends .of saidspindles are mounted hubsfi? carry-` f' y'70 ing pie holders 18` atl their tops. rlhe members 1li are preferably spacedapart at sub-` stantially equal distances'onthe conveyer 10.

Immediately above the parts 1l and rest-k ing` thereon l provide a plurality of plates l9ivhich are 'disposed in overlapping condition, as clearlyindicated. rlhe ends (of each plate-19iare rounded and one end of each plate provided with a-slot 20 and the other end provided with a substantially circular opening 21. The openings 20 and 21 are disposed about the spindles or shafts 16 so as to hold the plates 19 inV position. lt ywill be apparent that the slots 2O provide means for thejpla'tes `19 being movedy slightly longitudinally of each other wlienfpassing around with theconveyer l0.,` The slots 2O also fa cilitatethe attachment and removal of the platesoli. These plates 19 are of suilicient width to prevent the pie erusts and other foreign material from falling down onto the Atracks 11 and conveyer 10.

Securedto a part of the frame 12 is an upright .frame 23 near one end of the machine,

as clearly indicated in Fig. 1. ln this frame 23 isgan upright shaft 2li having connec-y tion with the conveyer lOso that one conial pletey rotationof shaft 24 takes yplace while the conveyer` moves a distance equal to the distancek between two oi the members 14.

Any suitable driving connection may be used as'desired. l have indicated a suitable connection comprising a sprocket 24' on shaft 24 and a sprocket 2li on the shaft of cutting wheel 13" with a sprocket chain 25 con-l mechanism is disengaged from the driving.

means by a manually operated clutch. ,A suitable form of clutch'is indicated Aby a member 28 splined on shaft 25 with a pr'ojec-v tion 29 adapted to engage a notch 30V in the hub of the gear 26 on shaft 25. l,The splined part 28 is also provided with a projection 31 adapted to 'engage a notch 32 in a bearing-.33

groove 34engaged by a lever 35 which is pivoted as at 36. A lever 37 is pivotedV as at 38 and has a spring 39 mounted on av rod 40, and the latter pivoted as at41to the lever 37. The rod 40 is slidably mounted ina head :42 which is pivoted in the end of lever 35l and spring 39V presses against said head 42 to cause movement of the lever 35. Stops 43 and 44 are provided to limitthe oscillatory movements of lever 37. The arrangement is such that spring39 tendsr to press the lever 35 in one.direction*when lever' 37 is engag# ing stop 44 and when lever.' 37 is swung on its pivot 38 to its dotted line position in Fig.

1 it rests against stop 43and tends to' press lever 35 in theV opposite direction. 'When lever 37 is engaging stop 44 spring 39 tends Vto hold projection '31 in the notch 32 of bearing 33, and when lever 37A is engaging stop 43 lever 35 tends to l-hold projection 29 in Vnotch 3() of the hub of gear 26. The space shaft 25 is at rest and it is desired to throw' itinto motionlever 37 is moved to its dotted` between hub of gear-26 and bearing 33 is such that member 28- andv one ofthe projections 29 or 31 can just rotatebetween said bearing 33 and 'hub of 'gear 26. Withthisf arrangement whenmember 28`is pressed to-` wardbearing 33 projection 31 will ride against the end of bearing 33 until it engages notch 32 when it will enter said notch and stopV rotation of shaft 25.V When member 28 fispressed toward gear 26 projection 29 will ride against the end of gear 26 until it engages notch 30 when it will moveinto said notch and canse member 28 to rotate shaft V25. With this arrangement when line position in Fig. 11 This causes member 28 to engage notch 30 to rotate the shaft.,

To disconnect the shaft 25 from the driving shaft24, the lever 37 is moved to shift the splined member`28out of engagement with the Vnotch 30 into engagement with the notch 32A of thebearing 33. This stops the Y shaft`25 and the crimping mechanism i'sso Vpie in pie holder 1 positioned with relation to shaft 25'that it will be out of the path of movement of a At the upper end of frame 23 is a guide 45 in which is mounted a block 46 and adapted Vfor lvertical movement. Attached to the tion with the bar 47, and hence horizontally,

so that it is substantially parallel with the upper surface of a` pie in the pie holder 18. The shaft 25 carries a crank pin-51 which is connected witha yoke 52, and the latter pivoted. as at 53 to the links 48. Secured to ofthe shaft 25. The splined part 28 has a the shaft 25 and rotatable therewith is a ,crank-pin wheel 51.1 which is interposed bevrpin wheel may be provided with a plurality of openings each at a diii'erent'distance from the axis of'shaft 25, .see Fig. 3, for receiving the crank pin 51 so as to vary the throw of the latter to adjust the movements of the crimping head 50.* This provides means for moving the crimper head v50 ina vcircular path and along with the pie holder during the crimping operation. One of the links 48 is provided with an arm 54, and pivoted to the arm 54 alink 55. The link 55 is pivoted to the middle part of a bar56 at its .lower end and the bar 56 pivoted to shanks 57 of stripping members 58 and 58. The shanks 57 are slidably mounted in upright openings in ears 59 on the crimper head 50'. A spring` 60 isV connected to one end ci bail "56 andthe arm 54 so that the stripper 58 is rocked downwardly below the surface Vof the crimper head`50, as clearly indicatedin Figs. V3, 4 andl 5. Also, connected with link 55 is a spring 61 which is mountedin such a manner as to take most of the weight of' crimper head 5() and its mounting from the crank pin 51 so as to facilitate easy and smooth movement of the crimper headin action. -The link 55 is provided with a slot 62-so-as to permit its movement on a pin 63V in the end of arm 54. 'As thecrimper 50 engages pie A, stripper 58 engages the pie before stripper 58 causing' spring'GO to lengthen and the link55 to slip upwardljT with the slot 62 sliding on pin63. Then as the crimper V50 is lifted from the pie, strip-A per 58 is lifted from the latter before stripperr 58 because of spring 60 and its manner of being mounted. ln Fig. 3 the crimping mechanism is shown in its position of rest. It will not matter when lever 37 is operated to throw thecrimping mechanism into and out of operative position. This mechanism will not be operative untilthe parts have reached their position shown in Fig. 3 either i in throwing the crimping. mechanism into or out of operative condition. ln Fig. 4 the crimping mechanism is shown in position with the crimping head engaging a pie l in the pie holder 18. ln Fig. 5 the parts are shown with the crimping head 50 just leaving the pie and the strippers 58 and 58 disengaging the pie and crimper head 50. lVithout these strippers the dough ot the crusts tends to stick to the crimper and tends to pull the pie out ot the pie holder or else tear the crusts. The spring 60 tends to hold the stripper 58 at the rear side oi the pie in engagement with the pie longer than the other stripper. This facilitates clearing the crimper head from the pie as the side et the crimper head adjacent stripper 58 tends to stick to the pie longer than the other side in:.use.

Adjacentthe pie-crimping mechanism on the trame 12 l provide a resiliently mounte'L track section 64 which is pivoted as at 55 on a member 66. The member 66 is provided witha slot 67 and member Gil provided with a bolt 68 mounted in the slot. Mounted in frame 66 is a screw 69having a restricted portion with a spring` 70 mounted in this portion and pressing upwardly on track Gil. Each ot the members 14 is provided with a roller 71 which is adapted to engage the track. With the resilient support under one end of track 6a this tends-to press the pie holder 18 up against the crimping head while a pie is being crimped, giving a resilient pressure between the pie holder a d crimping head.
